Novel neurostimulator device uses nasal cavities to stimulate tearsChronic dry eye disease (DED) affects more than 25 million people and to date the only pharmacologic therapies are topical or involve punctal plugs. Results from two studies wth a neurostimulator indicate there may be a new pathway to upregulate the body’s tear system.
Handheld polarizing filter augments corneal imaging with simple approachUse of a handheld circular polarizing filter to intercept afferent and efferent light from a slit lamp or operating microscope highlights corneal structures that are otherwise invisible or barely seen.
Expanded line of 27-gauge instruments advantageousThe portfolio of retinal instruments continues to expand with a growing line of tools offering surgeons improved work efficiency while promoting better surgical outcomes with 27-gauge instruments.
Integrating computer-assisted toric IOL implantation
Integrating computer-assisted toric IOL implantationSince making the switch to a markerless toric alignment system, Bryan S. Lee, MD, JD, explains how the technology has eliminated ink marking from his surgical regimen.
Novel forceps design improves iris hook placementNew forceps designed by Lawrence Goldberg, MD, improve the technique for iris hook placement due to two-point fixation.
Portable non-mydriatic device closes gap on tele-glaucoma screeningA portable non-mydriatic fundus camera was found useful in grading cup-to-disc ratio as part of glaucoma screening compared with a standard tabletop mydriatic fundus camera.
New drape speeds ophthalmic surgery
New drape speeds ophthalmic surgerySurgical draping for ophthalmic surgery has never been quick or easy—until now. A new drape design allows the surgeon or scrub nurse to fully drape the patient in seconds.
Ultrasound device capable of precise imaging, biometry of eyeEarly results from a repeatability and reproducibility study of a precision ultrasound device indicate the anterior segment imaging device can provide unique measurements on the cornea and will have multiple applications in the future.
Mobile refractive screening technology yields real-world applicationsThe advent of portable autorefractor technology may deliver autorefraction to populations that might not otherwise have any access to eye care.
Phakic IOLs address challenge of treating broad range of refractive errorsPhakic IOLs are viable alternatives for treating high refractive errors.
